These bio-based materials can be processed on standard injection-molding machines and extruders and can be recycled in the same recycling channels as conventional fossil-based polymers. Avient employs approximately 8,700 associates and is certified ACC Responsible Care®, a founding member of the Alliance to End Plastic Waste and certified Great Place to Work®.

A decrease in density of just 0.01–0.02 g/cc can yield 4% annual savings in material consumption, while generating a 4% increase in extruder productivity. This small drop can be a game-changer in efficiencies for a typical PVC extruder. This gave processors control over gauge, thickness and weight throughout the entire extruded part, all leading to improved performance and quality.

Working with virtually any thermoplastic base resin, we offer a complete line of existing plastic formulations for a comprehensive set of performance requirements.

However, this can negatively impact the mechanical and physical performance of medical plastics. They can be processed on standard injection-molding machines and extruders and recycled in the same recycling channels as conventional fossil-based polymers.   Avient is certified ACC Responsible Care®, a founding member of the Alliance to End Plastic Waste and certified Great Place to Work®.

In contrast, short fiber reinforced solutions are produced by introducing pre-chopped fibers (typically 1mm or less) into an extruder where the fibers are mixed with polymer and other additives.  Since fiber in long fiber composites is continuous throughout the length of each cut pellet, long fiber materials have a higher fiber aspect ratio than short fiber filled plastics.
